Amy has not seen herself yet but it's time. Show Amy her new look. Come on over. Oh, my god. Wow! Look at her. So what do you think? Come over. Oh, my god, I am amazed. How does it feel? Oh, my god. This is a dream come true for me. I don't know what to say. This is amazing. I don't know if you noticed your husband ray's face. I just fell in love again. Oh. Oh, my god. She looks amazing. You two go next to each other. I don't want to get in between that but ask Gretta. You look beautiful. Let's start with the clothing and congratulations, by the way, on your weight loss. Thank you. This was a big step taking the next step. Talk about it. Absolutely. She's lost 150 pounds. She is a mom of six and a grandmother to three and she is hot and rocking so what I had to do is lighten up her wardrobe. When you lose weight you can't get there and think you have to wear huge clothes. Take advantage of sunset color, instant bounce. Metallic shiny jewelry and also you got to go white jeans, if you can wear them like she can rock them do it. It's instantly youthful. So now hair, the hair is a big difference. Ted, the hair to me is -- was incredibly dramatic. You had that sort of '80s -- a lot of product. A lot of product. You know what's great about her in particular, 150 pounds. You have to give it to her. The fact you lose the weight you have to lose the hair. That bod is so hot and on trend and makes her look fantastic. I love it. How do you feel with shorter hair. I've never had hair this short before. It's amazing. And ray? She looks gorgeous. Gorgeous. Mally. The makeup is beautiful. It looks like less makeup. She was stuck in that '80s makeup. Dpashg liner. Made her eyes look like slits. No more. Beautiful light eyes. Brown eyeliner instead of black this time. Softer. Look at that beautiful face and she's alive and gorgeous and we love you.
